TRAETION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 357,978, dated February 15, 1887.

Application filed September 14, 1886. Serial No. 213,543. (No model.) I

To all whom it may concern.-

Be it known that I, Mnwxssnn A. CHAM- BERLAIN, a eitizen'of the United States, residing at Wild Cat, in the county of Riley and State of Kansas,have invented certain new and useful Improvements in Traction-Engines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part hereof.

The object of my invention is to so improve the traction-engine as that its several parts shall be of ready access, thereby making it under the more immediate control of the engineer, and by the addition of water-tanks and coal-bins avoiding the necessity of employing a team to accompany an engine and supply coal and water when on the road.

In the drawings, Figure 1 is a side view of a traction-engine showing my improvements. Fig.2 is a sectional view of the reverse side thereof. Fig. 3 is a detail front view of the guide-wheel, levers, and braces. Fig. 4 is a detail inverted view of the steering mechanism.

Similar letters refer to similar parts throughout the several views.

First, I reverse the action of the engine by placing the drive-wheel A and the motive gearing A, B, O, and D, together with the band-wheel P and fly-wheel F, at the forward end of the boiler, thus freeing the firebox H from the incumbrance of the heavy castings and rods heretofore interfering with the ready access to the same by the engineer, and leaving room for the construction of the coal-bin G on each side of said fire-box. Said boiler rests upon the saddle E, which in turn rests upon the axle N, and through which runs the counter-shaft M. The stringers u u, reaching from the saddle E and bolted to each side of the fire-box H, extend to the rear and serve as a bed for the platform, on which is placed the water-tank I. Said stringers also serve as a bearing for the axle of the guidewheels. Braces b I) extend one from each of the stringers to u to the bottom of the fire-box at s. For guiding the engine the drum. 0 is journaled between the stringers a a, near the rear ends thereof. Around this drum is wound the chain t t, both ends of which are attached to the axle w at its opposite ends. Said axle 'w turns upon the fifth-wheel y.

On one end of the drum 0 is affixed the gear (I, which is engaged by the worm-gear on one end of the horizontal rodf. At the other end of the rod f the bevel-gear 11 engages the gear 1-, which is attached to the lower end of the perpendicular rod L, the other end of which has attached thereto the bevel-gear O, which in turn engages the gear on one of the handwheels 2'. The journal-box e, which is held in position by the braces g 9, serves as a bearing for the shaft connecting the hand-wheels i i.

The object of the two hand-wheels is to avoid the reverse motion incident to the use of a single wheel when running the engine backward, and thereby also avoiding the danger of a false motion. For convenience, the steam and reverse leversl and 7a are placed within easy reach of the engineer while guiding the engine, the ratchets jj being secured to the arm 9', which is an extension of the brace g, and is firmly held in position by the brace g. Said levers are connected with the engine by means of the rods m and it.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a tractioirengine, the combination, with front and rear wheels, of a boiler having its fire-box located between said front and rear weels, a saddle, E, mounted in the engine-frame and resting upon the front axle, a counter-shaft, M, passing through said saddie, and motive gearing located at the forward end of the engine, substantially as and for the purpose described.

2. A traction-engine having a boiler, a firebox located between the front and rear wheels, a saddle, E, mounted on the engine-frame and resting on the front axle, a counter-shaft, M, passing through said saddle, and gearing A, B, G, D, and K, located at the forward part of the engine, substantially as described.

3. In a traction-engine having afire-box located between its front and rear wheels, coalbins G G, arranged upon each side of the firebox, a saddle, E, resting on the front axle and supporting the boiler, a counter-shaft, M, passing through the saddle, gears 13 and K on said shaft, and gears A O D, band-wheel P, and fly-wheel F, said gearing and wheels being ICO arranged upon the forward end of the engine, substantially as described.

4. The combination, with the traction-engine, of the steering-gear consisting of the drum 0, gear (Z, chain t t, rod f, having worm-gear a and bevel-gear 1), gear 1*, rod L, bevel-gear O, and journal-box 22, together with the handwheels i i, substantially as shown and described.

5. The combination, with atraction-cngine, 0f the braces g 9, one of which is bent to form the arm 9, and the ratchets j 7', secured to said arm, substantially as shown and described.

6. The combination of a traction engine MANASSEH A. CHAMBERLAIN.
